摘　　要：目前,车载用酒精传感器是智能网联汽车领域需要研究的重点之一。文章采用以尿素在加热过程中分解产生的气体为模板的软模板法,制备空心球结构的氧化镍,并探究表面活性剂十二烷基硫酸钠(SDS)在材料生长过程中的作用。通过XRD、XPS和SEM,对制得的样品进行表征分析,并用专业的测试方法对样品进行气敏性能测试,对比添加SDS与不添加时材料的形貌和气敏性能。结果发现,该结构材料对乙醇气体具有极高的灵敏度,以及良好的浓度线性响应信号,并且具有很好的稳定性,有望作为新一代车载酒精气体传感器的关键材料。Alcohol sensors used in vehicles are currently one of the key research areas in the field of intelligent connected vehicles.This article adopts a soft template method using the gas generated by the decomposition of urea during the heating process as a template to prepare hollow spherical nickel oxide,and explores the role of surfactant sodium dodecyl sulfate(SDS)in the material growth process.Characterize and analyze the prepared samples using XRD,XPS and SEM,and conduct gas sensitivity testing on the samples using professional testing methods.Finally,compare the morphology and gas sensing performance of the material with and without the addition of SDS.It was found that the structural material has extremely high sensitivity to ethanol gas,good concentration linear response signal,and good stability,which is expected to be a key material for the new generation of in vehicle alcohol gas sensors.
